Scientists have long been trying to understand why the Neotropical region holds highest diversity of birds on Earth. Recently, there has increased interest in morphological variation between and within species, how climate, topography, anthropogenic pressures may explain affect phenotypic variation. Because data are not always available for many species at local or regional scale, we limited our understanding intra- interspecies spatial Here, present ATLANTIC BIRD TRAITS, a set that includes...
Abstract Passive acoustic monitoring (PAM) is increasingly popular in ecological research, but recording and analyzing large amounts of data still a critical bottleneck for the long‐term multiple species. We evaluated how temporal spatial sampling effort affects species diversity estimates using set 14,045 1‐min recordings from various neotropical birds anuran communities. Our goals were to evaluate (i) daily vocal activity cycle anurans, (ii) effect structure (e.g., number minutes listened...
<title>Abstract</title> Under the current global biodiversity crisis, there is a need for automated and non-invasive monitoring techniques that are able to gather large amounts of information cost-effectively at scales. One such technique passive acoustic monitoring, which commonly coupled with automatic identification animal species based on their sound. Automated sound analyses usually require training detection algorithms. These algorithms annotated datasets mark occurrence sounds...
Passive acoustic monitoring (PAM) has become increasingly popular in biodiversity. It produces large amounts of data and can provide a foundation for understanding the long-term consequences environmental degradation. However, extracting biological information from such extensive datasets be challenging requires advanced computational skills. Herein, we introduce streamlined workflow detecting signals three critically endangered birds: Cherry-throated Tanager (Nemosia rourei), Alagoas...
Many factors could influence repertoire size and function. Here, we provide a review of the descriptions vocal repertoires New World jays unifying terminology for function their vocalizations. We summarized 19 different functional types behaviour shared by at least two species, purposes. Comparing 14 studied also classified vocalizations into four major classes defined priori: ‘Social Integration’, ‘Conflict Resolution’, ‘Predator-related’, ‘Breeding’. Cooperative breeding, as well group...
Human activities have modified landscapes worldwide, promoting fragmentation and isolation of forest habitats. Such landscape modifications are responsible for changes in species composition due to extinction colonization events. Forest dynamism is usually affected by when remaining fragments small isolated, but more stable large connected. In this study we verified bird during 23 years monitoring at the Mata dos Godoy State Park (PEMG). We aimed evaluate avian community reserve, as well its...
The abundance distribution of the tyrant flycatchers (Tyrannidae family) was evaluated in three main forest habitats Mata dos Godoy State Park (PEMG), north state Paraná. We conducted point counts and from collected data we calculated Index Point Abundance (I. P. A.) each species interior mature (FLI), slope (FLE) reforestation (REF). Among 22 recorded species, eight occurred all habitats, while other two six were exclusive one habitat. 16 more than habitat, 10 abundant only one. On contrary...
Underlying biological processes can often shape phenotypic variation. Although subtle, the variation in plumage colour of Azure Jay (Cyanocorax caeruleus) has long been suggested to be phylogeographic importance, but this hypothesis was not tested. This species’ distribution Atlantic Forest biome south-eastern Brazil is divided into two ecologically distinct portions by Serra do Mar mountain line. The availability Parana Pine (Araucaria angustifolia) seeds essential for survival Jays western...
